There's something for everyone in this week's must-have games roundup.

Kicking off this week’s must-have games roundup is a fantastic first-person shooter from the creators of Shadowgun, in which you must take down hoards of bloodthirsty zombies before they take control of planet Earth. We also have a wonderfully unique astronaut simulator called Astronaut Spacewalk, plus lots more.

I’m a huge fan of first-person shooters, and Dead Trigger is one of the most enjoyable I’ve played on iOS in recent times. From the creators of Shadowgun, Dead Trigger delivers stunning console-quality graphics with highly-detailed 3D characters and environments. It also promises more than 40 hours of gameplay, though I haven’t been able to confirm that myself just yet.

Your mission is to take down the bloodthirsty zombies in an effort to save the Earth:

In 2012 modern civilisation is coming to an end. Global economics have been disrupted, money has lost its value. People have risen against the ignorant politicians who were just lining their pockets – and they didn’t spare any of them.

However, those who really ruled the world were prepared – and escaped. Suddenly billions of people died from a strange virus, while others turned into butcherly beasts with just one thought:
TO KILL!

Dead Trigger’s creators are also promising even more content in its next update.

I wrote about Astronaut Spacewalk back in May, and I’ve been waiting for it to hit the App Store ever since. Why? Because it’s the first app for iOS — at least that I know of — that allows you to become an astronaut. And let’s face it, that’s every boy’s dream.

Created by independent developer Jorge Hernandez, Astronaut Space is an astronaut jetpack simulator, which allows you to control a Manned Maneuvering Unit (MMU) — the same booster-controlled suit used on NASA shuttle missions — to fly from the Space Shuttle cargo bay to different satellites. Once you get their, you’ll have to carry out 20 missions to align each one and make repairs.

This isn’t a pick-up-and-play game that you can jump in and out of while you’re out shopping and your wife is trying on clothes; it takes time and patience to get used to, but it’s definitely worth it.

Outwitters is a hugely addictive turn-based multiplayer game in which you “take turns maneuvering your troops in a race to destroy the enemy base.” There are three sides to choose from: the “snuggly-wuggly” Adorables, the robotic Feedback legion, or the seafaring Scallywags.

Battle against players of a similar skill in league play, against Game Center friends or random users in friendly play, or use just one device for “pass n’ play” multiplayer. Just be warned: Once you start playing Outwitters, it’s very hard to stop.

All you need to know about Captain Antarctica is that you play a penguin who rides an experimental jet-powered scuba suit that is fueled by fish. Your mission is to rescue your wife and children who have been kidnapped and you must tackle breakneck speeds as you travel through each level, battling bosses along the way.

Join Captain Antarctica on a breakneck mission and help him to overcome tons of devious enemies and obstacles. Destroy massive bosses and save your family and friend.

While you go deeper and deeper, make use of every crazy invention you can get! Inventor Ed has prepared powerful flashlights to overcome darkness; fish magnet add-ons, energy containers and some of the wackiest gadgets since the invention of fruit slicing. How about melon and cherry powered jet scuba suit?! Yeah…We have all that stuff.

Unlike Astronaut Spacewalk, Captain Antarctica is a perfect pick-up-and-play game that’s perfect for passing the time.

Deals of the Day

Astronaut Spacewalk looks interesting but it’s really poorly explained in the iTunes store as to what it is or how it works.

It seems to be a jetpack simulator for instance, but all the screen shots are 3rd person views? How can it be a simulator if it isn’t 1st person? And if it has a 1st person mode, why are there no screen shots of it, (it would be the main mode).
